Final Impression
Apologies to those who might have been anticipating a full-length, organized review from me on this amp, but I'm going to have to cancel it. A full review will not be coming soon or anytime in the future.
Final thoughts of this amp?
It's definitely a capable amp and it's driven everything I've thrown at it with relative ease, including the Grado HP1000/HP2; Audio-Technica ES7, AD2000, W5000, W2002; and AKG K701. The Klipsch IMAGE X10 and UE triple.fi 10 Pro too, though the IEMs did reveal some background hiss on the amp at high volume (no music playing but connected to source). In contrast, I clearly remember the HeadAmp Gilmore Lite as being completely silent throughout the entire volume range when I tested it with the Audio-Technica CK7.
The VHP2 has the sound of a basically transparent amp. More than once I felt like I was not listening through an amp, which made me recall my days almost two years ago with the HeadAmp GS-1. Clean & clear with a nicely polished tint.
Something about the amp feels slow though - I haven't gotten the impression that its speed is nearly as good as on a HeadAmp amp. In lieu of direct comparison I can't say this conclusively of course, but it does seem like it trawls over very fast notes. In reference to my previous balanced Beta 22 it's a definite step down (but then again I also listened to the B22 primarily in balanced mode so that's not a completely fair comparison).
Treble & bass extension is good but without another home amp for comparison I can't say anything conclusive here either. It hits low enough for standard purposes (and sounds fine with the AD2000) and goes high enough to at least sound clean around the edges. (I haven't formally critically listened to either aspect.) Soundstage too is wide, though the depth impresses more, it really enhances z-axis projection if it's on the recording and the source component carries it through.
I think the best thing I can say about the amp is that it sounds very good and can tackle the varied demands of different headphones with relative ease. It should be a fine solution for anyone who doesn't want to buy HeadAmp for one reason or another (probably the most notable issues being lead time and communication delays). Though in my personal case I vastly preferred the sound of HeadAmp's Gilmore Lite.
Build quality between the Gilmore Lite and VHP2 is relatively on level - both are tough and durable and are nicely finished. Both are cased in brushed aluminum chassis but the Gilmore Lite is completely & professionally sanded over (by hand, I might add) for a very smooth feel. Its form factor, loop output, and power switch give it an edge too, for me at least. The VHP2 has loop output too but its cubic shape and no power switch were definite turn-offs for me.
My personal recommendation: HeadAmp Gilmore Lite over the VHP2, primarily due to craftsmanship & build quality (lots of time obviously goes into individual Gilmore Lite amps), sound, and technical specs (there are more published specs of the Gilmore Lite/Dynalo than the VHP2, which show the GL as the more capable amp). Right now I understand that lead time is an issue when buying from HeadAmp, but whenever this is sorted out I see no reason to not recommend the GL over the VHP2.
I will post internal pics soon.
